.Application filed September 28, 1921. Serial No. 503,965.

To all whom it may concern."

Be it known that I, Fonnn E. BRANDT, a subject of the King of Sweden,residing at l/Vynton Works, tligh lVycombe, Bucks, England, haveinvented a new and useful 1V indow, of which the following is aspecilication.

It is the object of this invention to pro vide simple but novel meanswhereby a window sash may be raised and lowered, opened and closed by aswinging movement, and be held securely in any position which it mayassume.

t is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

In the drawings :Figure 1 shows in elevation, a device constructed inaccordance with the invention; Figure 2 is a longitudinal sectionshowing one sash in open position; Figure 3 is a fragmental front elevation wherein parts are broken away; Figure 4; is a section taken on theline l% of Figure 1; Figure 5 is an elevation showing one edge of theslide; Figure 6 is a section on the line 66 of Figure 3.

The numeral 1 marks a window frame carrying stop and parting strips 2defining guide ways 3 wherein slides 4, in the form of bars, are mountedfor reciprocation. Sashes 5 are disposed between the slides lVasherstrips 6 of any desired form are mounted on the inner edges of thestiles of the sashes 5. Pivot elements 7 are mounted in the stiles ofthe sashes 5 and in the slides 4, intermediate the ends of the stilesand the slides. lVing nuts 8 are threaded on the outer ends of the pivotelements 7 and are adapted to bear against the washer strips 6.Superposed nuts 9 are threaded on the outer ends of the pivot elements 7and are received for rotation in recesses 10 fashioned in the slides a.The outermost nut 9 has a kerf 11,

and the inner nut 9 may be similarl equipped, to the end that the nutsmay be manipulated by a spanner or like tool.

The stile of each sash 5 has one or more bores 12 adapted to be alinedwith bores la in the slides l. A washer plate 15 is mounted on the stileof each sash 5 at the end of the bore 12. A keeper plate 16 is attached.

by securing elements 17 to each slide 1 and has an internally threadedprojection received in the bore 14 of the slide 4:. Screws 18 arejournaled in the washer plate 15 and are provided with turning heads 19,the screws passing through the bores 12 and 14, and being threaded intothe projections 20 of the keeper plates 16.

The screws 18 serve to hold the sash '5 securely in a closed position,in alineinent with the slides l, :1 d under such conditions, the slidesand the sash may be reciprocated vertically, after the manner of acommon window sash. The screws 18 may be removed, whereupon thesash 5may be swung on the pivot elements 7, and be held in adjusted positionsby tightening the wing nuts 8. The sash, having been tilted, may beraised and lowered, along with the slides It is possible to reverse thesash 5 about a horizontal axis, if cesired. Especial attention isdirected to the fact that the nuts 9 are countersunk into the slides 4,the keeper plates 16 being countersunk likewise, and the construction ofthe slides being such that they may be mounted in any ordinary windowframe, without requiring any changes whatsoever therein.

I claim A device of the class described comprising a frame, slidesmounted for reciprocation in the frame, a sash mounted pivotallyintermediate its ends on the slides, the sash i11- cluding a stile, oneslide and the stile being provided with cooperating transverse bores,the bores being formed directly in said slide and said stile, each borebeing of a common diameter from end to end, both bores being of the samediameter, and the bore of the stile extending entirely through thestile, a plate countersunk into the outer surface of said slide andinterposed between said slide and the frame, the plate having anintegral internally threaded cylindrical projection extended toward aidstile into the bore of the slide and fitting closely therein, a washerplate secured to the outer edge of the stile and having an opening ofless diameter than the bore of the stile, the washer plate constitutinga closure for the bore of the stile, and a screw of less diameter thanthe bores, the screw being journaled in the opening of the washer plateand having a head adapted to engage the washer plate, the screw beingthreaded into the projection, and the washer plate serving to centralizethe screw with respect to the bore of the stile.

In testimony that I claim the foregoing as my own, witness my hand.
